I worked for Jasper for almost 6 years. I handled warranties for about 4. 5 of those 6 years. You would not believe the horror stories I could tell. Full warranty coverage, particularly labor reimbursement, is pending factory analysis of the failed unit. It seems that an abnormal number of their units fail because of "abuse", "cooler was not flushed/replaced", "towing in overdrive", "improper installation" etc. Basically, you are at their mercy, and if they can blame the failure right or wrong on the installer or end user they will. A large percentage of the warranty department phone grabbers are not even capable of changing their own oil, let alone helping you with a problem. Their performance ratings by their supervisors is based on how many times they can answer the phone in a day, not how many customers they actually help. The production management people don't want them built right, they want them built right now. You would be much better off with a trans from one of the builders listed in thew TDR links section or discussed frequently under various and numerous threads on this forum. Much has also been mentioned on these threads about service after the sale. One of these vendors would be my first choice, Chrysler Reman my second choice, and junkyard or used my third choice.
